CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 329,537, dated November3, 1885.

Application filed September 14, 1885.

To LZZ whom it may concern:

Be it known that I, GEORGE H. CoLBY, of Boston, in the county of Suffolkand State of Massachusetts, have invented a new and useful Improvementin Coupling Attachments for Locomotive-Tenders, of which the followingis a specification.

The object of my invention is to provide the guide-wing or projectionfor controlling the lateral movement of the hook end of the couplingdraw-bar of the car with an adjustable guide-bar or detachable device,whereby the coupling-hooks lmay be retained in position with each otherand the draw-bar hook of the car uncoupled therefrom when the car andtender are upon a short curve in the track by removing the detachabledevice, or adjusting the guide-wing laterally, as hereinafter more fullydescribed, and set forth in the claim.

This invention relates to an improvement in coupling attachments forlocomotive-tenders for which Letters Patent No. 288,209 were granted tome, dated November 13, 1883.

Figure l represents a perspective view of a coupling attachment forlocomotive-tenders having my invention applied thereto. Fig. 2represents a plan view of the same with the upper portion of the caseremoved therefrom.

A represents the lower part of the frame of a locomotive-tender at therear end, having secured thereto aguiding and supporting case, B, made,preferably, of cast metal, and bolted through its anges C to said frameat the rear end of the tender, as shown in Fig. l. A bunter-bar extendsthrough the upper part of this case, provided with a bunter-head, D, onits outward end, and with means fixed to the bar, and a coiled springsecured in position thereon, as heretofore and now in general use, sothat when the bunter is forced in the spring is compressed, and itsrecoil operates to force the same outward to its former position whenreleased. A coupling-bar, E, provided with a hook, F, at its outwardend, extends through the lower part of the said case B, and extendsbeneath the tender, and is secured or pivoted to the end of the shortspringbar portion, formed as usual, so that the hook end of the saidcoupling-bar may be moved in a lateral direction, and when forcedlongitudinally in either direction the spring will return the bar to itsnormal position when released. A ver- Serial No. 177,125. (No model.)

tical shaft, G, provided with ahand-Wheel, H, at its upper end, hassuitable bearings in the said case at the outside, with a ratchet-wheelsecured to the shaft, and a pawl pivoted to the case, and a chain, J,secured at one end to the shaft and at the other end to the saidcoupling-bar E, serves to draw the latter to one side when the shaft isturned and the said chain wound thereon, and the coupling-bar maybe heldin such position by the pawl engaging with the said ratchet in the usualmanner, so as to disengage the coupling-bar hook of the tender from thehook of the coupling-bar on the next car.

When it is desired to couple the locomotive and tender to the train, theformer, with its tender, is backed against the first car of the train,and as the curved outer ends of the coupling-bars come together they areforced laterally or to one side until the meeting-faces of the hookspass each other, when the hooks engage with each other in the usualmanner, and when it is desired to detach the locomotive and tender froma train the said Vertical shaft is turned by its hand-wheel to wind thechain upon said shaft, and the couplingbar, with its hook, is drawn toone side, so that the hooks will be disengaged, when the locomotive andtender are free to move away.

In order to guide the hooks into position with each other, so as toreadily couple together, I provide one side of the said case B with anextended or projecting'wing, K, opposite the face of the said draw-barhook F, which serves to guide the opposite coupling-hook on the carlaterally, so as to engage with the said draw-bar F when broughttogether in the usual manner. This guide-wing K also serves to preventthe coupling-hooks from becoming accidentally disengaged when passingaround a short curve in the track, and in practice it is found that inorder to best serve these purposes its position in relation to hooks ofthe draw-bars is such that the tender cannot be readily uncoupled fromthe next car when the saine are stopped upon a very short curve in thetrack, and in order to provide a remedy for this defect I provide theinward face ofthe said guide-wing K with a vertical dovetailed groove oropening,L, as shown, and fit therein a slightly-tapering detachableguide-block, P, which may be withdrawn from said opening IOO or groove Lwhen desired, so as to permit the draw-bar of the car to be forced toone side or laterally a sufficient distance to disengage the said hooksfrom each other when theloco- 5 motive-tender and car are at rest uponthe track, as above described, or Whenever desired, and as a means ofsafety and convenience I provide the said guide-block P With a chain, N,secured to the upperend thereof 1o and connected to the outside of thesaid case B, or in any other suitable manner. It will be evident thatthe said guide-Wing K may be hinged to the case B, and adapted to beadjusted laterally, and secured in such position I5 as desired, so as toserve the same purpose contemplated, as by the means of the saidremovable guide block P, Without in the least departing from myinvention.
